This generally means that cpp exited with some error, I think. (yes,
the error message could be improved.) I suggest to step with a
debugger through the relevant functions in cmacexp.el, it's possible
there's a bug there.
More to the point: I don't know what you mean, exactly, by "marked
HAVE_PWD_H with a region". For a C preprocessor to produce something
reasonable, the region you mark should be valid C, so you should at
least include everything to and including the matching #endif in the
region. If I do that, the command works for me, and produces a region
with the contents of <pwd.h> header, which means HAVE_PWD_H is defined
in my configuration.
